• 準備 ICAS, Crawlzilla, f-motif Demo VM

Ganglia

• Ganglia 設定檔參考 - Ubuntu karmic (9.04) 以後是 3.1.2-2 版本，且有 ​ganglia-webfrontend 套件，設定方式比較簡單。

  #### Server ####
  ~$ sudo apt-get install gmetad ganglia-webfrontend ganglia-monitor
  #### Client ####
  ~$ sudo apt-get install ganglia-monitor
  

• 把 ganglia-webfrontend 的 apache 設定檔連結到 apache2 的目錄

  ~$ cd /etc/apache2/conf.d
  /etc/apache2/conf.d$ sudo ln -s ../../ganglia-webfrontend/apache.conf ganglia-webfrontend
  /etc/apache2/conf.d$ sudo apache2ctl restart
  

• /etc/ganglia/gmetad.conf

  data_source "${YOUR_NAME} cluster" ${HOSTNAME}:8649
  trusted_hosts 127.0.0.1 ${HOST_IP} ${HOSTNAME}
  

• /etc/ganglia/gmond.conf
